FACE SHIELD AND ADBUSTABLE HEAD BAND THEREFOR Robert Malcom, Jr.,Chicago, 1li., assigner to Chicago Eye Shield Company, Chicago, lll., acorporation of Illinois y Application February 15, 1956, Serial No.565,572 11 Ciaims. (Cl. 2 9) The principal object of this invention isto provide an improved face shield and adjustable head band therefor,wherein the transparent face piece may be quickly and readily releasablysecured to thev brow piece of the face shield, wherein relative thermalexpansion and contraction between the face piece and brow piece isprovided even though the two pieces are firmly secured together, whereinthe face shield is pivotally mounted on the head band in a simple mannerto allow easy manipulation of the face shield, wherein the head band isquicklyv and readily adjusted to t the head of the wearer, and whereinthe head band is soft and exible withl no metal parts touching the headof the wearer so as to provide maximum comfort.

' Further objects of this invention reside in the details ofconstruction of the face shield and adjustable headband and in theco-operative relationships between the cornponent parts thereof.

Other objects and advantages of this invention will become apparent tothose skilled in the art upon reference to the accompanyingspecification, claims and drawing in which:

such as aluminum or the like. Rivets 19 extend through the holes 17 inthe brackets 16 and through the brow piece 12 for securing the channelmember 13 to the brow piece 12. Intermediate its ends, the inner leg 14is alsoV provided with a pair of holes through which rivets 20 extend,also for securing the channel member 13 to the brow piece 12. The outerleg 15 of the channel member 13 is provided with holes 21 in alignmentwith the intermediate rivets 20. A pair of spring members '23 providedwith holes 24 are secured in place on the brackets l 16 by the rivets19, which secure the brackets 16 tothe brow piece `12 being relativelystii and preferably being formed from plastic impregnated paper board orthe like.`

brow piece 12, and the outer free ends of the spring members 23 areprovided with inwardly facing buttons 25 which, in turn, extendthrough'the holes 26 in' the outer leg 15 of the channel member. Bymanipulating the spring members 23, the buttons 25 may be insertedthrough and drawn from the holes 26. v

A resilient transparent face piece 28, which may take the form of asuitable transparent plastic sheet, has its upper edge closely receivedinthe channel member 13. The face piece 28 is provided adjacent its endswith a pair of slots 29 which are in alignment with the pair of holes 26in the outer` leg 15 of the channel member 13. When the buttons-25 onthe spring members 23 are inserted through the holes 26 in the channelmember 13, they are alsoy snapped through the slots 29 in the tace piece28 for releasably securing the face piece 28 in place in the channelmember 13. By reason of the slots 29 the face piece 28 and the channelmember 13 are allowed to expand and contract with respect to each otherso that thermal expansion and contraction conditions will not operate todistort or buckle the face piece 2 8. When the face piece 28 isinsertedin the channel member 13, it is deformed slightly between theintermediate rivets 20 and the 'aligned holes 21 in the outer leg 15 ofthe channel member 13, which also operates releasably to secure the facepiece 28 in the channel member 13. In this way, the face piece 28 isquickly and'readily releasably secured in the channel member 13 and,hence, to the brow piece 12, and replacement of face piece is readilyaccomplished.

The adjustable head band ll'includes `an open ended flexible sleeve 32which is preferably formed of a soft llexible plastic material.V Thissleeve 32 has an inner wall 33 and an outer wall 34. The outer wall 34ofthe sleeve is provided intermediate its ends with a pair ofspaced-apart transverse slits 35, these slits dividing the sleeve into acentral portion between the slits and side portions between the ends oftheisleeve and the slits. An outwardly facing button 36 is secured tothe outer wall 34 of the central portion ofthe sleeve between the slits35. A flexible strap 38, preferably formed of a soft flexible plasticmaterial, extends between the open endsl of the sleeve 32 and has twoends 39 and 4l). The end 39 of the strap 3S is threaded through one sideportion of the sleeve 32, through one slit 35, over the outer wall 34 ofthe central portion of the' sleeve, and through the other slit 35 intothe other side portion of the sleeve 32. Inv a like manner the other end40 of the strap 38 is threaded through said other side portion of thesleeve 32, through said other slit 35, over the outer wall 34 of thecentral portion of the sleeve, and through said one slit 35 into saidone side portion of the sleeve 32. The ends 39 and 4t) of the strapoverlap each other and, as illustrated herein, the end 39 of the straplies inwardly from the end 40 of the strap. The ends 39 and 40 of thestrap 38 are each provided with a plurality of longitudinally spacedholes 41, which selectively receive the outwardly facing button 36carried by the outer wall 34 between the slits 35. By inserting thebutton 36 through the desired holes 41 in the strap ends 39 kand 40, the

encircling length of the strap 38 is quickly and readily adjusted.

The face shield is pivotally mounted on the adjustable head band 11 andthis is accomplished by passing rivets through the outer wall34 of thesleeve 32 adjacent the ends thereof and the holes 18 in the brackets16.1 Washers 44 and 45 are arranged ontV opposite sides of the vbrackets16 and are drawn up snugly by the rivets 43 so as to provide africtional type of pivoting action. By reason of these pivotalconnections between the adjustable head band 11 andthe face shield 10,the face shield may be readly'manipulated with respect to the face ofthe wearer.r Since the adjustable head band 11 is soft and liexible andsince there are no metal parts ,which can touch the head of the wearer,the face shield andadjustable head band of this invention may be worn'with maximum comfort.

While for purposes of illustration, fone form of this invention has beendisclosed, other forms thereof may become apparent to those skilled inthe art upon reference to this disclosure and, therefore, this inventionshould be limited only by` the scope-of the appended claims.
